I don’t want your confirmation. I want the team’s confirmation.
At the risk of being blunt, your personal guarantee doesn’t mean anything to me because I have no idea who you are or what your connection to Razia and the team is.
For instance, I could tell you that Vitaly Petrov will join Force India, give you my assurances that it will happen because I speak Russian, and you would have no reason to doubt me. Except that I’m an Australian high school teacher with no connection to any teams.
So you can understand why I don’t accept your confirmation – and there is nothing you can say that will make me believe it until (or if) Marussia announce it.
